SEC. 213. NONROAD ENGINES AND VEHICLES.
(a) Emissions Standards.- (1) The Administrator shall conduct a
study of emissions from nonroad engines and nonroad vehicles
(other than locomotives or engines used in locomotives) to
determine if such emissions cause, or significantly contribute
to, air pollution which may reasonably be anticipated to endanger
public health or welfare. Such study shall be completed within 12
months of the date of the enactment of the Clean Air Act Amend-
ments of 1990.
(2) After notice and opportunity for public hearing, the
Administrator shall determine within 12 months after completion
of the study under paragraph (1), based upon the results of such
study, whether emissions of carbon monoxide, oxides of nitrogen,
and volatile organic compounds from new and existing nonroad
engines or nonroad vehicles (other than locomotives or engines
used in locomotives) are significant contributors to ozone or
carbon monoxide concentrations in more than 1 area which has
failed to attain the national ambient air quality standards for
ozone or carbon monoxide. Such determination shall be included in
the regulations under paragraph (3).
(3) If the Administrator makes an affirmative determination
under paragraph (2) the Administrator shall, within 12 months
after completion of the study under paragraph (1), promulgate
(and from time to time revise) regulations containing standards
applicable to emissions from those classes or categories of new
nonroad engines and new nonroad vehicles (other than locomotives
or engines used in locomotives) which in the Administrator's
judgment cause, or contribute to, such air pollution. Such
standards shall achieve the greatest degree of emission reduction
achievable through the application of technology which the
Administrator determines will be available for the engines or
vehicles to which such standards apply, giving appropriate
consideration to the cost of applying such technology within the
period of time available to manufacturers and to noise, energy,
and safety factors associated with the application of such
technology. In determining what degree of reduction will be
available, the Administrator shall first consider standards
equivalent in stringency to standards for comparable motor
vehicles or engines (if any) regulated under section 202, taking
into account the technological feasibility, costs, safety, noise,
and energy factors associated with achieving, as appropriate,
standards of such stringency and lead time. The regulations shall
apply to the useful life of the engines or vehicles (as
determined by the Administrator).


264





(4) If the Administrator determines that any emissions not
referred to in paragraph (2) from new nonroad engines or vehicles
significantly contribute to air pollution which may reasonably be
anticipated to endanger public health or welfare, the Administra-
tor may promulgate (and from time to time revise) such
regulations as the Administrator deems appropriate containing
standards applicable to emissions from those classes or
categories of new nonroad engines and new nonroad vehicles (other
than locomotives or engines used in locomotives) which in the
Administrator's judgment cause, or contribute to, such air
pollution, taking into account costs, noise, safety, and energy
factors associated with the application of technology which the
Administrator determines will be available for the engines and
vehicles to which such standards apply. The regulations shall
apply to the useful life of the engines or vehicles (as
determined by the Administrator).
(5) Within 5 years after the enactment of the Clean Air Act
Amendments of 1990, the Administrator shall promulgate
regulations containing standards applicable to emissions from new
locomotives and new engines used in locomotives. Such standards
shall achieve the greatest degree of emission reduction
achievable through the application of technology which the
Administrator determines will be available for the locomotives or
engines to which such standards apply, giving appropriate
consideration to the cost of applying such technology within the
period of time available to
manufacturers and to noise, energy, and safety factors associated
with the application of such technology.
(b) Effective Date.- Standards under this section shall take
effect at the earliest possible date considering the lead time
necessary to permit the development and application of the
requisite technology, giving appropriate consideration to the
cost of compliance within such period and energy and safety.
(c) Safe Controls.- Effective with respect to new engines or
vehicles to which standards under this section apply, no emission
control device, system, or element of design shall be used in
such a new nonroad engine or new nonroad vehicle for purposes of
complying with such standards if such device, system, or element
of design will cause or contribute to an unreasonable risk to
public health, welfare, or safety in its operation or function.
In determining whether an unreasonable risk exists, the
Administrator shall consider factors including those described in
section 202(a)(4)(B).
(d) Enforcement.- The standards under this section shall be
subject to sections 206, 207, 208, and 209, with such modifica-
tions of the applicable regulations implementing such sections as
the Administrator deems appropriate, and shall be enforced in the
same manner as standards prescribed under section 202. The
Administrator shall revise or promulgate regulations as may be
necessary to determine compliance with, and enforce, standards in
effect under this section.
[42 U.S.C. 7547]
STUDY OF PARTICULATE EMISSIONS FROM MOTOR VEHICLES
Sec. 214. (a)(1) The Administrator shall conduct a study
concerning the effects on health and welfare of particulate

265





emissions from motor vehicles or motor vehicle engines to which
section 202 applies. Such study shall characterize and quantify
such emissions and analyze the relationship of such emissions to
various fuels and fuel additives.
(2) The study shall also include an analysis of particulate
emissions from mobile sources which are not related to engine
emissions (including, but not limited to tire debris, and
asbestos from brake lining).
(b) The Administrator shall report to the Congress the findings
and results of the study conducted under subsection (a) not later
than two years after the date of the enactment of the Clean Air
Act Amendments of 1977. Such report shall also include
recommendations for standards or methods to regulate particulate
emissions described in paragraph (2) of subsection (a).

HIGH ALTITUDE PERFORMANCE ADJUSTMENTS

Sec. 215. (a)(1) Any action taken with respect to any element
of design installed on or in a motor vehicle or motor vehicle
engine in compliance with regulations under this title (including
any alteration or adjustment of such element), shall be treated
as not in violation of section 203(a) if such action is performed
in
accordance with high altitude adjustment instructions provided by
the manufacturer under subsection (b) and approved by the
Administrator.
(2) If the Administrator finds that adjustments or
modifications made pursuant to instructions of the manufacturer
under paragraph (1) will not insure emission control performance
with respect to each standard under section 202 at least
equivalent to that which would result if no such adjustments or
modifications were made, he shall disapprove such instructions.
Such findings shall be based upon minimum engineering evaluations
consistent with good engineering practice.
(b)(1) Instructions respecting each class or category of
vehicles or engines to which this title applies providing for
such vehicle and engine adjustments and modifications as may be
necessary to insure emission control performance at different
altitudes shall be submitted by the manufacturer to the Adminis-
trator pursuant to regulations promulgated by the Administrator.
(2) Any knowing violation by a manufacturer of requirements of
the Administrator under paragraph (1) shall be treated as a
violation by such manufacturer of section 203(a)(3) for purposes
of the penalties contained in section 205.
(3) Such instruction shall provide, in addition to other
adjustments, for adjustments for vehicles moving from high
altitude areas to low altitude areas after the initial
registration of such vehicles.
(c) No instructions under this section respecting adjustments
or modifications may require the use of any manufacturer parts
(as defined in section 203(a)) unless the manufacturer
demonstrates to the satisfaction of the Administrator that the
use of such manufacturer parts is necessary to insure emission
control performance.


266


(d) Before January 1, 1981 the authority provided by this
section shall be available in any high altitude State (as
determined under regulations of the Administrator under regula-
tions promulgated before the date of the enactment of this Act)
but after December 31, 1980, such authority shall be available
only in any such State in which an inspection and maintenance
program for the testing of motor vehicle emissions has been
instituted for the portions of the State where any national
ambient air quality standard for auto-related pollutants has not
been attained.

promptly establish at least one testing center (in addition to
the testing centers existing on the date of the enactment of the
Clean Air Act Amendments of 1990) located at a site that
represents high altitude conditions, to ascertain in a reasonable
manner whether, when in actual use throughout their useful life
(as determined under section 202(d)), each class or category of
vehicle and engines to which regulations under section 202 apply
conforms to the emissions standards established by such
regulations. For purposes of this subsection, the term "high
altitude conditions" refers to high altitude as defined in
regulations of the Administrator in effect as of the date of the
enactment of the Clean Air Act Amendments of 1990.
(2) The Administrator, in cooperation with the Secretary of
Energy and the Administrator of the Urban Mass Transportation
Administration, and such other agencies as the Administrator
deems appropriate, shall establish a research and technology
assessment center to provide for the development and evaluation
of less-polluting heavy-duty engines and fuels for use in buses,
heavy-duty trucks, and non-road engines and vehicles, which shall
be located at a high-altitude site that represents high-altitude
conditions. In establishing and funding such a center, the
Administrator shall give preference to proposals which provide
for local cost-sharing of facilities and recovery of costs of
operation through utilization of such facility for the purposes
of this section.
(3) The Administrator shall designate at least one center at
high-altitude conditions to provide research on after-market
emission components, dual-fueled vehicles and conversion kits,
the effects of tampering on emissions equipment, testing of
alternate fuels and conversion kits, and the development of
curricula, training courses, and materials to maximize the
effectiveness of inspection and maintenance programs as they
relate to promoting effective control of vehicle emissions at
high-altitude elevations. Preference shall be given to existing
vehicle emissions testing and research centers that have
established reputations for vehicle emissions research and
development and training, and that possess in-house Federal Test
Procedure capacity.
